“…6). However, temperature in the boreal Baltic is much lower than in North America 28 which might affect R. cuneata reproduction 29 . The maximum age found for R. cuneata in Brandalssund and Tulka Byväg was 7 years, and in Sveden 6 years, indicating that these clams were recruited in 2014 or 2015 from parent populations that colonized this northernmost reported location a few years earlier (Fig.…”

Invasive species are often generalists that can take advantage of formerly unexploited resources. The existence of such vacant niches is more likely in species-poor systems like the Baltic Sea. The suspension feeding wedge clam, Rangia cuneata, native to estuarine environments in the Gulf of Mexico, was sighted for the first time in the southeastern Baltic in 2010 and a few years later in the northern Baltic along the Swedish coast. To explore possible competition for food resources between R. cuneata and the three native clams inhabiting Baltic shallow soft bottoms, stable isotope and fatty acid analyses were conducted. There was no overlap between R. cuneata and any of the native species in either stable isotope or fatty acid niches. This suggests efficient partitioning of resources; multivariate analyses indicate that separation was driven mainly by δ13C and by fatty acids reflecting diatoms and cyanobacteria, respectively (e.g. 16:1ω7 and 18:3ω3). R. cuneata reflected seasonal variation in phytoplankton more than other clams reflecting higher trophic plasticity. In conclusion, the addition of R. cuneata to the Baltic shallow soft bottoms suggests the existence of a vacant trophic niche in these sediment habitats, however the long-term effects on other species and nutrient cycling requires further studies focusing on the population dynamics of R. cuneata and its impact on the Baltic Sea ecosystem.

“…The age structure of R. cuneata populations in different areas varies and depends on environmental factors [52]. In newly colonized areas, it also depends on the timing [14].…”

“…For example, Solovjova et al [13] observed high mortality in the bivalves of the Curonian Lagoon at water temperatures below 5 • C. Thus, it seems that this parameter, together with the availability and quantity of food, is also decisive as regards the growth of these bivalves. This is especially true since R. cuneata has a high tolerance to salinity [52]. Wolfe & Petteway [10] indicate that the range of salinity in which the Atlantic rangia may occur is between 0 and 33‰.…”

The aim of this study was to determine the biological, morphometric, and shape characteristics of the bivalve Rangia cuneata in the initial phase of colonisation. A total of 504 specimens were caught for the study. Their average length was 31.06 mm (range 12.7–43.2 mm) and weight 6.0 g (0.5–15.3 g). The population was dominated by individuals of 25–30 mm and 30–35 mm in length and the age of 3+ and 4+. The standard major axis regression for measurable traits describing shell cross-section indicate the allometric nature of growth for most parameters. Elongation and convexity indices by age group indicate a change in the shell shape as it becomes more elongated and convex in individuals that have already reached sexual maturity. The collected specimens were of larger sizes compared to other Baltic populations of the species, and similar in size to populations found in the neighboring Pomeranian Bay. The increase in length of R. cuneata in the Oder estuary is smaller compared to the species native sites, probably due to the lower water temperature in the study area. Considering the invasive potential of R. cuneata, it seems necessary to monitor closely its population and distribution in the estuary of Western Baltic.

“…1). However, there are some suppositions that under specific circumstances population development may be limited by climate and salinity -harsh winters and low ions content (Tuszer-Kunc et al 2020). A drastic reduction in the abundance reported from the Vistula Lagoon after a relatively long winter of 2012/2013 suggests that winter oxygen deficiency associated with ice cover may also be critical for population development (Warzocha et al 2016).…”

New record of Rangia cuneata (Mollusca: Bivalvia: Mactridae) on southern coast of Baltic Sea (N Poland)

In February 2021 a valve of Rangia cuneata – a clam native to North America, was found in a new location on the Polish coast in Ustka Bay. After first records of this clam in Europe in 2005 in Belgium and then in 2010 in the Baltic Sea (Russian part of the Vistula Lagoon), an increasing number of new observations have been reported since. This indicates an effective dispersal of this alien species in the Baltic waters.
